To all whom it may concern it known that l JAE-{IN F. LIVELY, Men 1 theUnited lotates, residing at i in the county of London and iennessee haveinvented new and 'nproi'enients in DoonOperating m of which 'hefollowing is a wecnication.

Th inrention relates to improvements operating mechanism and has par ap'ilicaticn to a mechanism for ti the doors of hopper cars.

out the present invention, it so to provide an operating or gates ofhopper I such may he swung to sd positions and whereby the ecurely andpositively locked "ion to prevent the accidental provide a mechcrilieelwhereby he cars in ay he swung s and whereby aim to provide a mechforthwhich will emtures of simplicity ciliw which may he inl ma d at aminimum e);- l which will embody few parts and correlated and arrangedas; to re that ,io possibility of derangement to a zz'iinimum. p

ll ith the ahore and other objects in View,

th intention consists in the coi'istruction, 1 matron and arrangement ofparts hereinaitcr forth in and falling *ltlllll the "ncture, the sidegirders and 3 the inloor of the hopper chutesf Closing e of rich chuteis a gate pivoted at its movement, as is well known.

sely disposed alining hearings 5 and journaled within the hearings andcapable of rotation therein an actuating shaft (I extending transverselyof the car and havi the opposite extremities thereof jourlcd inhorizontally alining hearings dis- 2d a scent to the opposite sides ofthe Cal body and secured to the latter in some suitable manner. Fastupon the actuating it 6 and proiecting outwardly therefrom 1 T h ng theouter end thereof 0 provide a f0 ed pivot knuckle the opposite linihsthereof formed with aiming slots 9.- Mounted within the dots t "idcapable of sliding movement therein a pin 10 carried by a pivot knuc ledisposed between the limbs of the ioz'ked knuckle S and connected with.one nk The opposite end of the is formed with a pivot knuckle 13 betweenthe limbs of a forked knuckle upon ore end of an actuating rod 15. Theend l he rod 15 equipped with the nuckle lei: 1s curves. as at 16 to fit"d the shaft (3 while the opposite end xach rod connected throughsuitable 'ies thereto a. lug 18.

' in practice when the door or gate is open the arm "I and link 12 arecoextensive with each other and disposed upon one side of the actuatingshaft 6, while the lug 18 extends downwardly. On the other hand, whenthe shaft is rotated to swing the gate to closed position the arm '2'moves through an arc to the opposite side of the actuating shaft andthrough the mediiun of the link 12 exerts a pull upon the rod 15 toclose the gate. In the initial movement of the arm under the action oftlie'shaft the pin 10 rides from no end of the slots 9 in the forkedknuckle to the opposite ends of such slots and the lug 1S enters thespace between the limbs of the ZEOlXGd knuckle 1d behind the knuckle 13on the link while in the continued movement of the arm under the actionof the shaft the l8 engages the adjacent knuckle on the link and pullsthe actuatmg upper end for pending rem. the center sills l are I thelatter as clearly illustrated in Fig. 3.

In the movement of the actuating rod under the action of the lug 18 thecurved portion the chute.

16 of the rod fits about the actuatingshaft thereby throwing thepivotalconnection between the link and the actuating rod upon the sideof the actuating shaft opposite from the gate and below the center lineof such shaft. Thus, the parts are locked against accidental movementand the gate securely held in closed position.

In order to rotate the actuating shaft, I employ, in the presentinstance, a worm 19 journaled in bearings carried by a bracket 20suitably fastened to the lower wall of Fixed to the shaft 6 is a wormwheel 21 meshing w'th the worm 19 and inclosed by a casing 22 carried bythe bracket 20; Fast to the worm 19 is a crank handle 23 by means ofwhich the worm may be retated to impart motion through the worm wheel 21to the actuating shaft 6. It will be seen that when the worm is rotatedunder the action of the crank handle 23 the worm wheel will be revolvedwith the effect to rotate the actuating shaft 6 so that theoperating-and locking mechanism of the door will be actuated aspreviously described, while the worm wheel being fast upon the shaft andmeshing with th worm will act to hold the shaft in any desired positionthereby enabling the gate or door to be opened to any extent.

While I have herein shown and described onepreferred form of myinvention by way of illustration, I wish it to be understood that I donot limit or confine myself to the precise details of constructionherein described and delineated, as modification and variation may bemade within the scope of the claims without departing from the spirit ofthe invention.

I claim:

'1. In a door operating mechanism for hopper cars, an actuating shaftcapable of rotation, an arm fast to said shaft and extending outwardlytherefrom, a link con in the closedposition of the door whereby thepivotal connection between said link and I rod will be disposed upon theside of the center line of said shaft oppositefthe door.

to lock the door against opening movement, and a lug extending outwardlyfrom said shaft at an angle to said arm and adapted to engage the armend of said link in the closing of the door to actuate said rodindependently of said arm. 3 e

2. In a door operating mechanism for hopper cars, an actuating shaftcapable of rotation, an arm fast to said shaft and extending outwardlytherefrom and having the outer end thereof formed to provide a forkedpivot knuckle, a link having one end thereof equipped with a pivotknuckle lying between the limbs of said first knuckle, a pin and slotconnection between said knuckles, a pivot knuckle on the opposite end ofsaid link, said link lying upon said arm when the latter is at one sideof said shaft and coextensive withsaid arm when the latter is at theopposite side of the shaft, 1 a door actuating rod having one endthereof of said rod behind the link pivot knuckle therein to actuatesaid rod independently of the arm.

in testimony whereof I aifix my signature in presence of two witnesses.
